Method for preventing and/or treating viral infection in aquatic animals

Abstract

The present invention provides a preferred method for preventing and/or treating a virus infection in aquatic animals, including the steps of: (i) providing a composition including trichoanguin protein; (ii) adding the composition to an aqueous solution including aquatic animals; and (iii) exposing the aquatic animals to the composition; wherein the composition is added in an amount effective to prevent and/or treat the virus infection. Preferably, the trichoanguin protein is provided by a transgenic plant.

       6. The method of  claim 3 , wherein the trichoanguin protein is provided in the form of the transgenic plant itself, a part of the plant, fruit, leaves, stems, tubers, seed or extract thereof. 
     
     
       7. A method for inhibiting white spot syndrome virus infection in shrimps, comprising:
 (i) providing a composition comprising a transgenic plant that expresses trichoanguin protein, or a part of the transgenic plant that expresses trichoanguin protein; 
 (ii) adding the composition to an aqueous solution comprising shrimps; and 
 (iii) exposing the shrimps to the composition, 
 wherein the composition is added in an amount effective to prevent and/or treat inhibit the virus infection. 
 
     
     
       8. The method of  claim 7 , wherein the composition is a feed composition. 
     
     
       9. The method of  claim 7 , wherein at least one portion of the transgenic plant is edible. 
     
     
       10. The method of  claim 7 , wherein the transgenic plant is selected from the group consisting of tobacco, potato, zucchini squash, tomato, lettuce, white grape, banana, rice, radish, carrot, apple, soybean, corn, and berries. 
     
     
       11. The method of  claim 7 , wherein the trichoanguin protein is provided in the form of the transgenic plant itself, a part of the plant, fruit, leaves, stems, tubers, seed or extract thereof. 
     
     
       12. A method for inhibiting nervous necrosis virus infection in fishes, comprising:
 (i) providing a composition comprising trichoanguin protein; 
 (ii) adding the composition to an aqueous solution comprising fishes; and 
 (iii) exposing the fishes to the composition, 
 wherein the composition is added in an amount effective to prevent and/or treat inhibit nervous necrosis virus infection. 
 
     
     
       13. The method of  claim 12 , wherein the composition is a feed composition. 
     
     
       14. The method of  claim 12 , wherein the trichoanguin protein is provided by a transgenic plant. 
     
     
       15. The method of  claim 14 , wherein at least one portion of the transgenic plant is edible. 
     
     
       16. The method of  claim 14 , wherein the transgenic plant is selected from the group consisting of tobacco, potato, zucchini squash, tomato, lettuce, white grape, banana, rice, radish, carrot, apple, soybean, corn, and berries. 
     
     
       17. The method of  claim 14 , wherein the trichoanguin protein is provided in the form of the transgenic plant itself, a part of the plant, fruit, leaves, stems, tubers, seed or extract thereof. 
     
     
       18. A method for inhibiting nervous necrosis virus infection in fishes, comprising:
 (i) providing a composition comprising a transgenic plant that expresses trichoanguin protein, or its-parts a part of the transgenic plant that expresses trichoanguin protein; 
 (ii) adding the composition to an aqueous solution comprising fishes; and 
 (iii) exposing the fishes to the composition, 
 wherein the composition is added in an amount effective to inhibit the nervous necrosis virus infection. 
 
     
     
       19. The method of  claim 18 , wherein the composition is a feed composition. 
     
     
       20. The method of  claim 18 , wherein at least one portion of the transgenic plant is edible.
